' WALDRON, a citizen of the United States, and

a resident of New Brunswick, in the county of Middlesex and State of New Jersey, have invented a new andlmproved Adjusting Device for Printing-Blocks, .of which the following is a full, clear, and exact description.

The printing-blocks with whichlinoleumprintin machines are supplied are of considerab e length, and consequently are apt to bend,'so that parts of the printing-surface are impressed .with too much force upon the fabric and other parts are either impressed too lightly or do not print at all.

' The principal object of my invention is to rovide means for adjusting the printingblock in such a manner that the several parts thereof can be forced outwardly or inwardly in order to overcome defects due to bending and to present an even printing-surface.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all theflgu-res.

Figure l is a planV of a plate supporting a printing block for linoleum-printing machines. Fig. 2 is alongitudnial sectional view of the same.V Fig. 3 is a sectional view on the line 3 3 of Fig. 1, and Fig. 4 is a sectional view on the line 4 4 of Fig. 1 on an enlarged scale.

The block a is connected with the plate b at a plurality of points, and the connections made between the two elements are of such a nature as to provide for adjustment, so thaty the block can be placed at a greater distance from the .plate at one place than at another, if desired. In order to accomplish this result, I place a nut or bushing c in a screwand a, respectively, with their surfaces flush 'ments' in the desired position.

manner', so as to provide as near as possible tions between the plate and block, located at intervals along the adjacent surfaces of the Vvwith each other the boltv da can be passed through the screw and into the nut, with the collar or washer d resting on-the top of the head of the screw, so Vas to secure the parts together. If itis desired to force the block and plate away from each other at this point,

the bolt is loosened and the screw e operated to project against the nut and force these elements apart. Then the bolt is again tightened, and it will hold the several eleparts-of the block may be adjusted in this an even printing-surface on the opposite side.

Having thus described my invention, I claim as new and desire to secure by Letters Patent` 4 1. The combination of a printing-block, aplate for supporting it, and a plurality of means for securing the block to the plate, said means being located at intervals along the plate, and each having means for moving the block both-toward and from the plate .and securing it in an adjusted position.

2. The combination with a printing-block for linoleum-printing machines, of a plate for supporting the block, and a series of connecplate and block each of said connections comprising means for vforcing the block both toward and from the plate and thus adjusting the distance between the block and plate.l `3. The combination of a printing-block, a

plate for supporting it, a. screw adjustably mounted on the block, and means adjustably mounted on the plate for vbearing against the screw and limiting its motion toward the block.- c

4. The combination of a printing-block, a` nut'or bushing mounted thereon, a supporting-plate, an adjustable element mounted on thev plate, and a bolt having means for bearing against the rear surface of the said element and adapted to engage the nut or bushing in the block to provide an adjustable connection between the block and plate.

k5. The combination of a printing-block for linoleum-printing machines, a nut mounted therein and provided with screw-threads, a plate, a hollow screw adjustably mounted on said plate and projecting through it to the The several surface adjacent to the surfaee of the block, l low screw and engaging said s`e`ewth1ezided 1o and a holt having a, collar engaging said screw opening and the opposite end ofthe screw.

and a screw-threaded portion engaging the l In testimony whereof I have signed my screw-threaded opening of the nut forlooking name to this specification in the presence of 5 the parts together two subscribing witnesses.
